DescriptionBACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to fasteners, and more particularly to a fastening for securing hooks and eyes, buttons, studs, etc. to a garment, the fastening having at least two spikes projecting from a base for being pierced through the garmentand for being clenched at the underside of the garment.
2. Prior Art
As shown in FIG. 1 of the accompanying drawings, known hook and eye members 1, 2 have fastening means which comprises a flat base 3 and a pair of flat spikes 4, 4 projecting perpendicularly from the base 3 for being pierced through a garment andthen for being clenched at their tip end portions, to take a hasp (not shown) at the underside of the garment. However, because of its merely flat configuration, the prior fastening tends to be easily bent or otherwise deformed around the shoulder orjoint between the base 3 and the respective spike 4 when the latter is pierced and clenched, especially if the garment is made of twilled thick fabric such as denim. With this arrangement, accurate and stable attachment of the hook and eye members 1, 2is difficult to achieve.
SUMMARY OF THE INVENTION
According to the present invention, a garment fastening comprises a base, and at least two flat spikes initially projecting from the base for being pierced through a garment into apertures of a hasp, and then for being deflected into a clenchedcondition against the hasp at the underside of the garment, there being at least two cold-pressed grooves each opening into an outer surface of the fastening and extending longitudinally thereof across a shoulder or joint between the base and arespective one of the spikes. The fastening hence has a greater hardness in a region around the grooves than at other regions thereof.
It is therefore an object of the invention to provide an improved fastening, for use on a garment, which is resistant to bending or other deformation around the shoulder or joint between a base and a respective spike when the latter is piercedthrough the garment and is then deflected to take a hasp at the underside of the garment, thus enabling easy and accurate attachment of hooks and eyes, studs, buttons, etc. to the garment.
Many other advantages, features and additional objects of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying drawings in which preferred embodimentsincorporating the principles of the present invention are shown by way of illustrative example.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of a hook and an eye, each having a prior art fastening;
FIG. 2 is a perspective view of a hook and an eye, each having a fastening embodying the present invention;
FIG. 3 is a perspective view, showing a modification of the fastening;
FIG. 4 is a cross-sectional view taken along line IV--IV of FIG. 2, showing a groove of rectangular cross section;
FIGS. 5 and 6 are cross-sectional views similar to FIG. 4, showing variations thereof; and
FIGS. 7, 8 and 9 are perspective views illustrating the manner in which the hook and eye are progressively assembled with their respective companion hasps.
FIG. 2 shows a hook 10 and an eye 11, each having a fastening embodying the present invention. The fastening comprises a flat base 12, and a pair of flat spikes 13, 13 initially (FIGS. 2 and 7) projecting perpendicularly from the base 12 forbeing pierced through a garment (not shown) into a pair of apertures 15a, 15a of a hasp 15, as shown in FIG. 8, and then for being deflected into a clenched condition at their tip end portions against the hasp 15 at the underside of the garment, as shownin FIG. 9.
As better shown in FIG. 2, the fastening of each of the hook 10 and eye 11 has a pair of grooves 16 each opening into an outer surface of the fastening and extending longitudinally thereof across a shoulder or joint 17 between the base 12 and arespective one of the spikes 13. The grooves 16 of FIG. 2 have a rectangular cross section. Alternatively, the grooves 16 may be of a semi-circular cross section (FIG. 5) or a triangular cross section (FIG. 6). Further, the two grooves 16, 16 of oneand the same fastening may be united at their confronting ends in the base 12, as shown in FIG. 3.
The fastening may be made of stainless steel, brass or other suitable metal. In production, the grooves 16 are formed by cold pressing to make the fastening harder in regions around the grooves 16 than at other regions thereof. This coldpressing not only increases the yield and tensile strength of the fastening around the grooves 16, but also reduces the ductility of the fastening around the grooves 16.
Having such cold-pressed grooves 16, the fastening is resistant to bending or other deformation at the regions around the shoulder or joint 17 between the base 12 and the respective spike 13 when the latter is forced through a garment and is thenclenched to take the hasp 15 at the underside of the garment, thus enabling easy and accurate attacment of the hook 10 and eye 11 to the garment with adequate firmness even if the garment is made of twilled thick fabric such as denim.
Although various minor modifications may be suggested by those versed in the art, it should be understood that I wish to embody within the scope of the patent warranted thereon, all such embodiments as reasonably and properly come within thescope of my contribution to the art.
